VANDAL demo video

December 18, 2008

Sit back, grab some popcorn, and get familiar with VANDAL’s guitar preamp & power amp modes, stomps, post fx (delay, reverb) etc.

Our current development state, brought to you by Dimitar Nalbantov:


Listening tests – part I

December 15, 2008

We could have long and exhausting talks over guitar amplification and such. But that’s pretty pointless if one doesn’t hear how things do actually sound.

Here are a few snippets of ‘VANDAL in action’, played by the brilliant Dimitar Nalbantov (

Simulating speakers & cabinets – part II

December 15, 2008

cabsim_spkbal_enclbalIn the VANDAL cabinet simulation, we divide the process into speaker and enclosure, and model both parts seperately. This is a flexible approach that lets the user choose even untypical combinations of both components.

But this calls for all kinds of interaction and is asking for trouble, as we will see.

Simulating speakers & cabinets – part I

In this section, we’ll talk about ‘impulse responses’ as the hottest shit on the market. But we’ll also get our feet wet, wading through Physical Modelling Land, trying to understand what all this blahblah has got to do with recreating guitar tones. Roll up your sleeves…

GUI evolution

December 9, 2008

Some things go pretty fast actually.

We really had a clear idea of how VANDAL should look like. Certainly not like any other guitar modelling software. Unique, but simple. Easy on the eyes.
Sure, one quickly argues about details as soon as more people get involved into the project. But as the following pics show, only small things got changed as we moved along: Read the rest of this entry »

How to build a VANDAL guitar amp…

December 9, 2008

Although we’ve planned to offer a guitar amp AND a bass amplifier, only the guitar amp is currently implemented. Unless we’re sure we’ve nailed it, all talk here remains highly guitar-biased for the time being.


If you’d unmount the case of a VANDAL guitar amp, you’d notice it contains typical tube circuitry to some extent and is in many ways comparable to popular designs known from famous stuff. But we’ve also thought of going an own route whereever it seems worth it, in order to create new tones or expand the amp’s flexibility.

Of course there’s no ‘case’, there are no ‘tubes’, no ‘circuit’ and other things we could touch (or burn our fingers at). This is all virtual. This is analog modelling.

While these days, everybody’s claiming to do such kind of DSP wizardry, we’ll hopefully manage to prove that we are serious here, by presenting the underlying technology in its whole beauty. Let’s hope this doesn’t get too boring…
The reason why we only concentrate on one amp currently is that we want to get its interiour right.

The main concept of the VANDAL guitar amp is a virtual circuit that models 3 different preamps and 2 different power amps, accessible via mode switches and a single clearly laid-out front plate: Read the rest of this entry »

How it all began… part II

December 8, 2008

The reason to carry on working on a virtual amp was a private issue: My V-Amp 2 was okay, although not perfectly suited for guitar AND bass. Something was missing. Not in terms of features, it was more about ‘tone’. Same with the other native amp sims, always way too sterile, one-dimensional. Or they put too much strain on my ancient Athlon XP. Plus, bass players rarely get as much attention as the guitar people.
At least, any work on this is going to be fun and there’s tons of things to learn ‘, I thought.
